CVE-2019-2569 in Oracle
Summary
by MITRE
Vulnerability in the Core RDBMS component of Oracle Database Server. Supported versions that are affected are 11.2.0.4, 12.1.0.2 and 12.2.0.1. Difficult to exploit vulnerability allows high privileged attacker having Local Logon privilege with logon to the infrastructure where Core RDBMS executes to compromise Core RDBMS. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized access to critical data or complete access to all Core RDBMS accessible data. CVSS 3.0 Base Score 4.0 (Confidentiality impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:H/UI:R/S:U/C:H/I:N/A:N).

The vulnerability identified as CVE-2019-2569 resides within Oracle Database Server's Core RDBMS component, representing a significant security weakness that affects specific version releases including 11.2.0.4, 12.1.0.2, and 12.2.0.1. This vulnerability classifies under CWE-284 which specifically addresses improper access control mechanisms, making it a critical concern for database security implementations. The affected system components operate at a foundational level within Oracle's database architecture, where the flaw manifests as a privilege escalation opportunity that could potentially allow unauthorized access to sensitive data repositories.
The technical nature of this vulnerability requires a high level of privileged access to exploit effectively, specifically demanding local logon privileges to the infrastructure where Core RDBMS executes. This prerequisite aligns with ATT&CK technique T1068 which focuses on exploit for privilege escalation, and the CVSS vector analysis reveals that the attack requires human interaction from someone other than the attacker, indicating a social engineering or insider threat component. The difficulty to exploit aspect suggests that while the vulnerability exists, it would require specific conditions and potentially coordinated actions to successfully compromise the system. The CVSS 3.0 base score of 4.0 reflects the confidentiality impact with a high severity rating, indicating that successful exploitation could lead to unauthorized access to critical data or complete access to all Core RDBMS accessible data.
From an operational impact perspective, this vulnerability presents a substantial risk to organizations relying on Oracle Database Server for their data management needs. The potential for unauthorized access to critical data represents a serious breach risk that could affect sensitive information including financial records, customer data, intellectual property, and other confidential business information. The fact that this vulnerability requires human interaction suggests that it may be susceptible to insider threats or social engineering attacks where an individual with legitimate access could be manipulated to facilitate exploitation. Organizations utilizing affected Oracle Database versions face significant risk of data compromise and potential regulatory violations if this vulnerability is not addressed through appropriate remediation measures.
Mitigation strategies for CVE-2019-2569 should prioritize immediate patching of affected Oracle Database Server installations to the latest security patches provided by Oracle. Organizations should implement strict access control measures and monitor for unusual activities that might indicate exploitation attempts, particularly focusing on local logon activities and privilege changes. The implementation of principle of least privilege should be reinforced to minimize the potential impact if exploitation occurs, ensuring that local logon privileges are strictly controlled and monitored. Additionally, organizations should conduct comprehensive security assessments of their database environments to identify and remediate similar vulnerabilities, while maintaining detailed audit trails to detect any unauthorized access attempts. The vulnerability's classification under both CWE-284 and its CVSS scoring indicates that it requires immediate attention from security teams to prevent potential data breaches that could result in significant financial and reputational damage to affected organizations.
